'Ihe headpiece also carries attachments,3.5i and 31 and has radiallugs38 and 39v onl the headwto engage with stop ,40 on the frame to arrest the swing of thehead at the points whereattachiments 36 and 31 axially alinewith the` cartridge case. v The cap 4` is screwably fastened to the` reduced threaded part 38a of theboss 30 and ooncentricallyvscrewedinto saidlcap is a screw 4|. Said screwand the reduced .portiony of said boss aresuciently milled outto provideV a ball .seatA forgthe ball ,42 whereby whlenthe cap `is screwed to said.V reduced4 portion said ball `will. properly aline. theY abutting faces of the turret and- `cap. v

, Attachment 35 'is the diein whichthe cartridge,

case is .resized, decapped'and the mouth thereof is belled.. Attachment 35 carries. the vpowder measuringand `charging device.` Rotating-*the lever 43 of the-powdercontainer 44 causesv the charge of. powder contained therein to be emptied thruthe attachment 35.in to the shell. Attachment 31 contains the bullet seating die in which the bullet is a o seatedlpriorr toits insertion in the she11, ,`UV v tappedinto the'turret; headpiece 3v and are' correctly positionedv both radially'and circumferentially Ato' insure that when said turret isfV swung Said die portion near its upper end into which is screwed the resizing and belling die member 48.

In Fig. 2 is also included a cartridge shell C and the upper portion of the adapter I l which is shown in the position it assumes as it decaps the primer cap 49.

The die 35 of Fig. 3 consists of an externally screw threaded sleeve 5| whichv is screwed into andextends thru the turret ange 3b. Said sleeve is provided with a knunee head 52 having adiametrically reduced 'upper extension 53 to receive the lower end portion of the powder magazine member 44. vThru said head and its exfitensio'n.-v 53 extends the powder feeding bore or passage 54 into the lower portion of which the shell isnprojectedincident to loading.

'The' bullet seating die shown in Figs. 4 and'5 comprises an externally :screw 4threaded cylindrical sleeve or casing 51 which is screwed into a screw-threaded bore provided therefor thru the turret flange 3c, ar lock nut 58 serving to secure said sleeve in its adjusted position. Y v

Into said sleeve screws an elongatedbullet seatingdie 59. 'I'he .lower end of said die is concaved asV shown at 60'in order to conform to the ogival contour of the nose of the bullet B.

v A bullet ejecting rod 59a .slidably ts within thebullet seating die 59. Said rod not only serves to eject an impacted bullet, but also indicates the lpresence of a bullet. Ify a bullet becomes jammed inthe die, said rod may be operatedto ejectit. I

,--Owingto the loose iit of said rod within the bore. which it occupies an airvent is provided therearound vwhich prevents a vacuum from being formed above the bullet. A vacuum might cause the bullet tol withdraw from the shell on attempting to remove the latter.

The cylindricalldie sleeve or casing 51 is p rovided with means for mechanically centering the bullet B.l Said centering means includes a series kof balls Gl each of said balls having, a seat 52 which is deep enough to allow the inner side ofthevball therein to protrude beyond the inner periphery'of the sleeve. Said seats 62 are formed in the bottom of a circular groove 63, and within said groove is seated a resilient snapv ring 64 which'yieldingly opposes the radial extensiony of saidy balls ,asy the circumferentially grooved bullet B is urged into place between them. When the bullet has thus been forced into rposition to be operated upon by the die, said balls enter the grooves of the bullet and accurately centers and aligns as shown in Fig. 4.v Y

' Describing more in y*detail the adapter IIv in which the shell casing C is mounted incident to being subjected to the various operations in the working cycle-said adapterfis provided with a reduced portion whichis fitted snuglyeinto the bore ofthe oiTset portionflll of the crosshead.A the terminal portionof vthe adapter which protrudes thru the bore being threaded and has screwed thereonto a nut 10 whereby the adapter is rigidly secured to the crosshead.

The adapter is provided with means whereby a cartridge container may lbev detachably secured therein, said means including a ysemi-circular in'- ternal groove 1| into which the crimped rim of4 thev closed end of the cartridge shell is inserted, andan emergency withdrawal slot 12 (see Fig. 1) to provide an unobstructed exit for the primer in case fouling causes the primer vto protrude. y

The major operations employed in the working cycle of rreloading a redrshell will now be described.

AThe` primer caphavng ,PQYuSly been insertedin the a primer cup, by further depressing the handle I6 the cap4 in the cup is caused to be .seated in the,I

hole oflthe case provided therefor.

The turret `is then swung until attachment 35 is alined with the shell, whencethe operating handle I6 isagain elevated and the charge of powder isernptied fromthe powder container 44 into the shell. `The operating handle is thereupon permitted to recede sufficiently' to permit withdrawal of the shell from the attachment.

The turret is again swung until attachment 31 is alined with the shell whence the operating handle is again elevated `Thisoperation brings `the loadedshell intothe bullet seatingdie, which has previously been suppliedwith a bullet B,and

`the bullet is forced intojthe shell, completing'the cycle. l
